Insulation in Western Switzerland — Free Quote
L'isolation thermique est la mesure de rénovation énergétique la plus efficace pour réduire la consommation de chauffage en Suisse. Elle peut concerner la toiture (le plus rentable), les murs extérieurs (façade ou isolation par l'intérieur) ou le plancher bas. Le prix indicatif varie selon le type d'isolant (laine minérale, PSE, PIR, cellulose), l'épaisseur nécessaire et le mode de pose. En Suisse romande, des subventions cantonales importantes sont disponibles pour l'isolation des éléments de l'enveloppe du bâtiment.

How insulation works proceed in Switzerland
During the first visit, the tradesperson assesses the condition of the surfaces, measures the areas to be treated and identifies any constraints — moisture, cracks, substrate type. A detailed written quote is delivered within 48 hours, specifying materials, number of coats and execution timeline. For a standard 80 m² flat with walls in good condition, work typically takes 3 to 5 working days with a two-person team. During the works, furniture is protected with dust sheets and passageways are kept secure. At completion, the tradesperson carries out a joint inspection with the client to verify the quality of the finish and resolve any outstanding items before signing the acceptance record.
Regulations and standards in Switzerland
In Switzerland, interior renovation works are governed by SIA 118 (construction contract) and SIA 243 (tiling). Any load-bearing wall removal or structural modification requires a building permit issued by the municipality. The Code of Obligations (CO art. 371) provides a 5-year warranty for hidden defects. For works touching insulation or technical installations, the cantonal energy regulations (RCEn) apply. It is recommended to use companies that are members of the Swiss Contractors Association (SSE) to guarantee compliance with professional standards.
Budget and tax deductions
Maintenance and renovation costs for a rented property are deductible from taxable income in all French-speaking cantons. For owner-occupiers, maintenance expenses (restoration, painting, like-for-like replacement) are also deductible. Capital improvements that increase the value of the property are, however, not deductible. For significant works, it is possible to spread the deduction over several tax years. Consult a licensed fiduciary to optimise your tax return, especially if you are combining maintenance works and value-adding works on the same project.
